Combination of Bacillus Licheniformis and Salinomycin: Effect on the Growth Performance and GIT Microbial Populations of Broiler Chickens
The beneficial effects of Bacillus spp. probiotic preparations used for poultry are well-documented and characterized by growth performance improvement and positive modulation of gastrointestinal tract (GIT) microbiota. Moreover, the favorable influence of salinomycin has been frequently studied as an ionophore coccidiostat. However, limited data are available in terms of the parallel usage of both Bacillus licheniformis DSM 28710 (B-Act®) and salinomycin in poultry diets.
From a practical point of view, evaluating the potential interactions between this species and agent is crucial to asses their parallel usage, and the current study confirmed the positive effect of their mixture on the modulation of pH value in the crop and ceca, as well as the GIT microbiota, especially in the jejunum and ceca. Additionally, the results obtained in this study show positive effects of B. licheniformis on the growth performance, as well as the influence of both experimental factors used separately in the case of GIT microbiota modulations.
